-Use the keys:
+## Building
 
-x - left
-c - right
-k - up
-m - down
+* Build libpayload
+* Start from `coreboot/payloads/pacman` or edit the `lpgcc` path in Makefile
+* Run `make`
+* Build coreboot with `An ELF executable payload`, pointing to the built
+`pacman` file. So far, it's only been tested in qemu.
 
+## Playing
+
+Run `qemu-kvm -bios coreboot.rom -M q35`. Use the keys:
